What you know, alibiers. Welcome to another episode of Pretty Lies and Alibis. I'm Gigi. It's Thursday,

May 29. Sorry I didn't get the recap in yesterday, but I knew today was a half day, so I thought I would

just combine both. This testimony for me personally was a little bit hard to follow at times due to all

of the math and the data that they were referring to.

So I wanted to make sure I went back and rewatched a few things I wasn't clear about

and just throw it all together and do a bigger one today.

We had Judson Welcher from Aperture back on the stand.

He was on direct exam at this point very briefly before we went over into

Cross. The state asked about the pain on his arm while doing these tests, and the witness said

the paint never went on the underside of his arm. And the SUV's damage is consistent with a

collision with John, and it would account for him hitting his head on the ground very hard.

As far as side swipes, what's being hit doesn't accelerate at the same speed of the object that hits it.

There is no complete momentum transfer and this leads to little damage being left on the car. It makes it hard for him

to compute force with these types of collisions. When someone is hit by a side swipe, it doesn't

show the broken bones that a direct hit would, and again, says steps taken by the person being hit would determine ultimately where they land.

On cross, they go into the witness's conclusions that weren't based solely on the physical data,

and witness statements were taken into consideration when the witness made decisions.

Both the witness and the defense agree that the goal of scientific methodology

is to reach their conclusion without bias. The witness is asked if one of the first questions he asked is how did this happen.

He says that's actually one of his last questions. When he starts, he has several hypothesis in mind, and as more information

comes in, he may have even more hypothesis in mind when he is investigating a case. The defense

points out that Aperture was hired by the Commonwealth two and a half years after John's death
